HANGER Eo FREIGHT-CAB noo s- Be it known that we, AMOS O. BANKs and GEORGE E. "BANKS, citizens of the United States, the'former residing at Baltimore city, and the latter in Brunswick, in the county of Frederick, and State of Maryland, have inthe following is a specification.

Heretofore in the construction offreight car' doors and vtheir hangers'of thedouble-= wheel classithas been the practice to provide a boxing for the lower track wheel in the side next to thehanger, this boxing being made slightly in curvilinear form. In order to apply these hanger plates it has been foundnecessary to out out "a portion of the door of the-car at the top. Whenthese hanger plates are placed in position the curved side of the boxing is thrown against the track, and when a car is loaded with a shiftingload and pressure is brought to bear against the doors the entire pressure comes against the bottom of the boxing at the point of connection with the hanger plates, this" point of connection being the most vulnerable or weakest point and it is liable to either bend or break and in either case it would render thedoor 1111-" serviceable.

To overcome these and'other objections is the purpose of our present invention which is ,an improvement upon Letters Patent granted to Amos 0. Banks and John J.

Tatum, No. 896,265, dated August '18, 1908.

Our invention relates to improvements in frei htcar door hangers, and has primarily for ts object dispensing with the cutting out of a portion-of the door. at its top in order to form .a boxing or housing for a smaller and lower track wheel, and also providing theup'per lugs .of the hanger plate with guides formed 'inte rally with and at the upper ends of said ugs.

With these and other objects in view the invention consists in the-novel construction and combination of, parts as will be herein aftermore in detail described and the asserted novelty -specifically. claimed- W have fully and clearly-'llustrated our invention in the accompanying drawings, in

edge view taken on the line 1-1, of Fig. 2,

and Figs. 4 and 5 are detail views.

"Similar letters of reference denote similar parts in the several figures.

' Referringto the drawings; A indicates it portionof a car and B-the door thereof,

both of which being of the ordinary, construction form no part of our invention.

C" designates a hanger plate provided with upper and lower lugs E, F, G, H which are formed integrally with the body or castin of the hanger plate, the upper lugs G an H- terminating in rearwardly rojecting bearing flanges I, I and friction ugs I I,

Formed integrally- -with the'body of the hanger plate is an oiIset arm formingwith I said plate-a boxing J, within which a. wheel K, is rotatively'mounted, a slotted flaring an nulus L being formed' upon the inner face of the ofiset within which loosely engages a slightly flaring or corresponding hub M formed upon the side of the wheel K adja- -cent to the oifset or boxing. Upon the opposite side of the wheel is likewise formed an annulus N and throu h the alined o .enings '0 and .P respectively'm the offset an wheel is passed a shoulderedaxle Q, having upon its inner end a. flattened head and upon its opposite or outer end abutton shaped head, the flattened head seated in the annulus N, In the lower portion of the offset or boxing is formed an o enin gfor a purpose which will be hereinafter explained.

The upper portion of this ofi'set arm terminatesin a hood R within which is rotatively I mounted. but out 'of alinement with the or side ofthe hood.

' X designates a Z-shaped track, the depending portion of which is interposed between'the upper and lower wheels, and it is also interposed between the outer face, of the hanger plate and the inneriace of the offset arm respectively and upon'whichthe wheels travel, and as before stated the wheels .lower and smaller wheel another and larger muc location and the unnecessary handling of the being out of ali n'ement they both-bear upon the -track, the upper one upon the horizontal portionand' the lower one upon'its dependg the door from contacting with the'rail or track "thus relieving the door from all wear and tear; while atthe same time the position guides I, I; simplify the application of the angler to the door to-a' great extent inasas measuring position and distances of door is an advantage of thefirst importance -as it also saves and reducesthe cost of appglin the hangers tofa minimum. The ction of, the bottom; wheel is such that when the "door lifts in opening or closing,

this wheel will come in contact with the lower edge of the rail and prevents the door from binding orlocking itself. The openin the lower end of the offset-allows afi edgeasclearly shown in Fig. 3 of the v drawings. y

' v The frictionlugs I T of the hanger plate serve the purpose of preventing the face of \Inelted snow and water to pass out fromthe parts of .the device that mayenter therein from without, i

Having thus described our invention what I we claim as new and desire to secure by Letters- Patent, is

The combination with a car and car-door;

of, a hanger plate having upper and lower lugs, bearing flanges, and friction lugs formed inte al track located above and adjacent to the upper lugs and -their., f iction lugs, an oflfset armformed integrally with the hanger plate therewith, a Z-shaped' having a slightly flaring annulus formed upon the inner face of said offset arm, a wheel hating ahub formed thereon upon'its side adjacent to the inner face of the .oifset arm to operatively engage theslightly flaring annulus formed upon its op osite side,

'a flattened headed shouldered ax qengaging said annulus, said ofiset arm havingwa hood formed upon the upper end thereof, and a wheel journaled in the hood, allarrangedand operated-substantially as'described, and

for the purpose set forth. A
